Should accept spaces after commas in notification tags

[raine]

We were wondering why the following wouldn't work, as only #jenkins appeared in tags.

So the tags literally have to be just comma-separated, like jenkins,develop,$Site. Not a big deal but looks like comma-and-space separated values are quite common in Jenkins, so I think it's easy to get this wrong.

Hi @raine,

I think #14 is ought to fix this exact problem. I'll try to check it today.
